YARN-STRiPPER.

SPECIFICATION forming part of Letters Patent N0.334,904, dated January26, 1886.

Application filed February 15, 1834. Serial No. 120,848. (No model.)

To aZZ whom it may concern:

7 Be it known that I, ALFRED SHAvnmol' the city of Troy, county ofRensselaer, State of New York, have invented new and useful Improvementsin Yarn-Stripping Devices, of

which the following is a specification.

My invention relates to that class of devices which are used to freeyarn from bunches, knots, and excrescences that are liable to be 13produced on it while it is being spun. These stripping devices areusually made from a piece of sheet metal that is provided with a slitfor the passage of the yarn, the edges of which slit tear off from theyarn,while the lat r 5 ter is being drawn through it, the knots orexcrescences upon it.

The object of my improvement on this class of devices is to adapt thestripping-slit to better retain the yarn within it, and to combine withthe stripper a means to return the yarn to the slit should it from themotion of the reciprocating yarn-guide be drawn from or run out of theslit.

Accompanying this specification, and forming part of it, there is asheet of drawings containing three figures illustrating my invention,with the same designation of parts by letter-reference used in all ofthem.

Of these illustrations, Figure l is a perspective of a part of abobbin-winder, with my invention applied thereto. Fig. 2 shows aperspective of my improved device, illustrated as removed from thewinder and upon a larger scale than it is shown at Fig. 1.

3 5 Fig. 3 illustrates a cross-section taken on the line 00 00 of Fig.2.

The several parts of the stripping device and those of the windermechanism with which the former connects are designated by letter- 0reference, and their function is explained as follows:

The letter F indicates the frame of that part of the winder mechanismthat is illustrated; the letter T its upper cop-table, and T" its lowerbobbin-table.

The letter R designates the tension-regulating pin-rod, and P the pin.

The letter A designates a preliminary stripping device, which may beused in connection with my improved device for the same purpose, ifdesired, and it is made of the ordinary construction having the slit a,and it is shown as attached to the cop-bonnet c.

The letter G indicates a yarn-guide, which at its end is connected withcrank K, and the latter at its lower end with the rock-shaft D, the saidrock-shaft being constructed to be reciprocatingly rotated so as toimpart a reciproeating motion to the yarn'guide G.

The letter B designates the bobbin, and b the conical presser. I

The letter S indicates my improved stripper, which is shown as formedwith the usual stripping-slit, S made in the plate E.

The letter S designates an offset made on 6 the under side of thedevice, and this offsetis constructed with a passage-way, S", and asetscrew, S for attachment and detachment.

The upper face of the plate E is flat, and the outer front edge thereofis curved, as ind i- 7 cated at m, and in operative connection the plateis adjusted on the yarn-guide rod with its face in a horizontal plane,the curved outer edge operating to guide the yarn back into thestripping-slit should it by any means dur- 7 ing the reciprocation ofthe yarn-guide and attached stripper be drawn from the slit.

The operation of my improved stripper and the parts with which itconnects is as follows: The yarn having been led from the cop O, aroundand over the tension-regulating pin P to and through the upper stripper,A, and thence through the slit S of my improved stripper, is wound on tothe bobbin B by the rotation of the latter. As the yarn-guide G isreciprocated to lay the yarn evenly on the bobbin-barrel, my attachedstripper also moves with it in reciprocation, and by which motion theyarn within the slit is also moved back and forth therein in a line ofmotion 0 that is opposite to that of the reciprocating yarn-guide andattached stripper. This lat eral movement of the yarn while passingthrough the slit increases the effiiciency of the latter to remove theknots and bunches on the 5 yarn while passing through the slit. If fromany cause the yarn thus moved in its passage is carried from out of theslit, on the return movement the curve m guides it back therein.

If desired, the upper stripper, A, may be IOO omitted and the yarn leddirectly from the tension-pin to my improved device.

1? make no claim to the form of slit herein shown with beveled edges,for any of the ordinary stripping-slits may be employed. To attach myimproved device, the latter is entered on the guide-rod and secured inplace by the set-screw S Havingthus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. In combination with the rock-shaft D, provided with the crank-armK,and the yarnguide rod G, connected to the crank-arm, the yarn-stripperS, consisting of the horizontal plate E, having slit S", curved outeredge, m, and sleeve 8, with set-screw S substantially as described, andfor the purpose set forth.

2. The combination of acop-bonnet, ayarnstripper secured thereto, atension-regulating rod provided with means to give tension to the yarn,a yarn-guide rod and a yarn-strip 20 per secured thereto, and abobbin-spindle, substantially as described, and for the purpose stated.

3. The combination of the bobbin-spindle, guide-rod G, and means forreciprocating the same, and yarnstripper S, secured to said rod, withcop-bonnet c, yarn-stripper A, secured thereto, and thetension-regulating pinrod R, substantially as and for the purpose setforth.

Signed at Troy, New York, this 1st day of February, 1884, and in ourpresence, whose names were by us hereto written.

ALFRED SHAVER.
